Avoid deleting of WBS elements when Project created using the Template

Hello Friends,

I have a requirement when project in PS is created using a Standard WBS (Template) i should not allow the users to make any changes in the project structure. I should not allow to delete any WBS elements from the Standard structure. How this can be achieved. Is it possible to Stop from the template that the structure should not be changed.

Any suggestions on this will be helpfull.

Thank you.
